• Thermal testing to be completed at DL this week• Installed in RR2 by end of October• AC supplies and water cooling required in RR2• Cable interconnections – need to be installed and terminated

SS Energy Absorber Rack

• Water connections changed from imperial to metric

• Insulation enhanced – maintaining thermal conductivity and electrical isolation

• Each diode module tested thermally to ensure optimum torque applied

• Water cooling arrangements agreed and installation initiated in RR2

• The water cooling will be maintained for a minimum of 1 hour during a loss of supply

• This will ensure the energy stored in the super conducting magnets is safety discharged.

DC magnet and Control Cables for SS & FC

• DC link boxes designed and delivered to RAL.• Currently installing DC link boxes / cable

management on upper South mezzanine.• There are 14 x 240mm2 and 4 x 70mm2

cables from RR2 to link boxes to install.• DC cable installation will require 4 staff due

to length and weight. Possibly completed before January.

• Controls cabling needs to be installed from RR2 to magnets - approx. 40 multicore cables with connectors.

• Estimated to be completion including terminations by end of February.

• Final dressing of cable / cable management installation after PRY installed is approx. 3 weeks.

• Preparation under way for testing in November.• Final installation is in RR2 and will require installing / terminating

cables to Hall.• Assemble second tracker control crate.

Tracker Install For November

Tracker 1Rack to be Re-Used, expanded to cover two Cryostats 1 & 2

Tracker 2 Rack Installed in Hall, but will use Tracker control crate destined for RRM2.

All control will be via VME interface in temporary rack as for single Cryostat tests.

All Cryostat interlocks will be cabled locally in the Mice Hall & available for tests, as envisaged for final install.

After Hall tests on all four Cryostats, control crates will be relocated to RRM2.

It will include Vacuum control for Turbo & Roughing pump.

Working closely with Craig for planned tests.

Compressor and Vacuum Rack

15

• Vacuum / compressor rack positioned as shown.

• Sumitomo compressors relocated and some cable management installed.

• Cryomech compressors powered and control cables installed, but need terminating.

Compressor and Vacuum Rack

• Vacuum Specification has been finalised.

• Rack design should be completed within next 4 weeks.

• Rack hardware has already been assembled.

• Rack wiring will take a further 4 weeks.• Electrical commissioning expected in

January.• Delivered to RAL by the end of January.• Install vacuum cables and terminate in

Hall – some work completed prior to rack delivery?

• Commission Vacuum and compressor systems.

Summary

• Control & Magnet PSU’s racks are progressing well, currently under test at DL.

• Cable management is well underway in the Mice Hall.

• Compressor power requirements are covered, controls to complete.

• Tracker testing in the hall is currently being finalised, with local/remote monitoring.

• Main cable install will commence when Magnet termination boxes are sited.

• Instrumentation cabling will follow, any last minute requirements please.

• Should be on program target, but a lot to do!!• Questions!!
